Well, he threw his helmet at an umpire. Now in many ways this incident wasn't nearly as serious. You can view the bat-throwing incident on YouTube. No such free video seems available yet on the Williams helmet toss, but Bernie merely tossed his helmet backwards in disgust. It didn't quite hit plate umpire Charlie Relaford, and didn't seem like it was particularly intended to. Likewise, it seems likely there'll be further penalties issued.
